T all. whom it may concern."

F. CLARKE, residing at Franklin, in the county of Venangoand Be it known that I, FREDERICK State of Pennsylvania, have invented oer-- tain new and useful Improvements in Means for Delivering Cutting Compound to the Tools of Vertical Boring and Turning Mills, of which the following is a specification.

- .The object, construction and use of this invention are herein-set forth with sufficient clearness-to enable those skilled in the'construction and operation of machine tools,

especially, vertical boring and turning mills, to make and use the same. I I

- equip The object of this invention is,-to provide means for the delivery of cutting compound to the tools of a boringmill or to; the work adjacent to said tools and to delivery pipe or nozzle will automatically follow the movement or travel ofthe tool in either vertical, horizontal or. intermediate directions in which" it may be feed-actuated,

tools, as the work proceeds.

= A further object of this invention is, to

the ram of a'vertical boring and t'urn- M j h cludes both. Furthermore it is immaterial ing mill with a fluid delivery means, in sue a way that it will not interfere with free access to the work-carrying table, or: re quire that said delivery means be move out of the way for the purpose of placing work upon :the table,.or,removing it therefrom.v

One form ofconstruction wherebyl .am

able to attain said object is'clearly illustrated 1 in the accompanying drawings, of which are as follows:,

the figures Fig. 1 is a front elevation of the cross rail 'of 'a boring mill=equipped with two saddles, each of which stantially the usual construction;

Fig. 2 is a side elevation of a vertical boring and turning mill equipped with my improved means of delivering cutting compound to the tools. I

- Fig. 3 shows a modified method of connectin the delivery conduit to the ram of the mi so connect the. .same to the tool-carrying elementthatthe dispense with the necessity of manually adjusting and re-ad ustmg. said nozzle, relative to the travel of the d tical position, or some carries a ram of. subconduit 10, theupper ings are illustrative merely, and show one way in which my'invention may be practically embodied. Furthermore, t it is ING COMPOUND are THE TOOLS or VERTICAL BORING Patented Aug. 15; 1 922.

pointed out that, whileFig. 1 shows two.

tionhas been applied, but my inventive idea I is as completely expressed in its japplication to one ram asit is when applied to two rams. As usual the precise definition and scopeof my invention must be found in the appended claims. a

The construction illustratedin said draw-.

ings is as follows: i

The cross-rail ofia vertical boringEand: turning mill 1 s equlppedwith two saddles 2 and 3, which-are mounted to. move-longi tudinally upon said :riail.

and turning mill it is a common prac the tool-slide with; a 'turret 1 In'the respective. i saddles is mounted a verticallyv movable ofwhich is shown'as carry cessively applied to the Work, and .my invention appl esasreadily to oneform of. l

such construction as to the other and'inso far as the application. of myinvention 1s concerned whether the ram occupies .ja'v'erposit on at an angle thereto..

.In order to prevent an excessive .gener a= tlon of heat by the operation ofthe cuttingit is necessary to *fio'od tools upon the work,

the cutting .edge of'the. tool,and.;..the area 1 adjacent thereto .with some of the "various oils or other fluid compoundscommonly used.

for this':purpose,.and my invention, which relatesto an equipment whereby, said cutting compound is, now be described. 7 j I r A's. usually constructed. the ram ofafbon. ing mill ishollow, or'provided witha core chamber 9, as shown in Fig.

end of which projects above the top of the ram. At a suitable point said pipe 10'extends throu h the front wall of the ram, through a suita leopening delivered to the tools, will- 1;within said chamber 9, is lnserted a suitable pipe. or

which intersects chamber 9, and the projectingportion or nozzle 10 of said pipe has its lower delivery-end positioned in close proximityto the cutting tool 8. The connection 11 is such that the pipe 10 may be swung vertically or laterally as desired, and isprovided with a suitable valve or stop 12, for regulating the flow of fluid through the pipe, and to shut off the same when desired. The upper end of pipe lOis provided with a swing joint 13, to which, in turn, is connected aconduit having suitable flexibility as a pipe 14 providedwithsuitable swing joints, l5 and 16; The outer flexible point 16, or the pipe which carries the saIne, is connected to the end of the cross-rail 1, in any suitable manner, as by a bracket 1-7. It will be noticed that the swing joints 16, 1-6, are connected by means of a supply pipe 18, butthis would not be used in a boring mill equipped with but one ram. I

In Fig. 2, the swingjoint 16', is shown as being carried by a T 19', to which is connected one end of a flexible conduit 20, the other end of which is connected to the outlet of a rotary or centrifugal pump 21; the driving pulley 22 of this pump is belted to a pulley 23, which is mounted upon the main driving shaft of the boring mill. The flexible conduit 20 permits the vertical travel of the cross-rail and the swing joints connecting the pipes 141 permit both a vertical and av lateral movement of the tool-slides ployed, the hole in the spindle of the table 2 is plugged so that the fluid supplied through the nozzle 10 cannot escape there through, and-a suitable channel 25 is pro vided upon the bed of the mill into which the cutting compound drains, and from 1 which it flows through the pipe 26 to a well 27, and into which the intake pipe 28 of the pump 21 is inserted, and draws its supply of fluid. r In Fig. 3'1 have shown a ram, in which a core-chamber 29 is utilized as a portion of the conduit for delivering fluid to the nozzle 10, thus dispensing with the section 10 of said conduit;

I am aware that it is not broadly new to supply means for delivering cutting compound to the tools of various machine tools, it is not my" intention to broadly claim myginvention in connection with machine tools in general; but, so far as I am aware my invention as herein illustrated, described, and defined in the appended claims, provides a more facile, economical and ellicient equipment of this kind than has heretofore been applied to a vertical boring and turning mill.

l clainr the following: v

1. l /ieans for delivering cutting compound to the tools of vertical boring and turning mills comprising a tube carried. in the tool-slide oi the mill, a delivery tube adjacent the tool carried by the slide said delivery tube attached to the slide and communicating with the tube in the slide, a main delivery tube attached to the machine and aflexible tube connection between the tube in the tool slide and the main delivery tube.

2. Means for'delivering cutting compound to the tools of vertical boring and turning mills comprising aslide for carrying the tool, a conduit in said slide for'the compound, a delivery nozzle carried by said" slide having communication with said con duit with its delivery end positioned ad'- jacent said tool, and flexible tube connection for delivering the compound to the conduit in said slide' Y I 3. Means for delivering cutting com'- pound to the tools of vertical boring and turning mills comprising in combination, the tool slide of such mill provided with; a conduit for the passage of the compound therethrough, delivery nozzle carried by said slide in communication with said con d'uit positioned exteriorl'y to the tool'with its delivery end' adjacent the cutting point of said tool so as to deliver said compound thereto, and flexible tube connectionar ranged to deliver the "compound to the conduit.

1. Means for delivering cutting compound to the tools of vertical boring and turning mills comprising in combination, the tool slide of such mill provided with a conduit for the passage of compound therethrough, a delivery nozzle carried by said slide in communication-with said conduit, positioned outside the transverse plane ofthe tool with its delivery end adjacent the cutting point of said tool, and flexible tube connection 'arranged to deliver thecompoundto said conduit. I

In testimony whereof I aflix in presence of two witnesses.
